4. Start-Up And Operation
4.1 Start-Up
Before using the humidifier, check the following:
 Supply and drain connections.
 That the cut-off tap is open.
 All wiring.
 Earthing.
 Steam hose connection between steam cylinder and distributor.
To start the humidifier simply switch on the air conditioner, which will in turn automatically start and stop the humidifier
as required. The (adjustable) parameters which determine humidifier operation have already been factory-preset (see
iCom manual).
4.2 Operation
Water, provided it contains even a small quantity of salts in solution, is a conductor of electricity. Therefore, if the
steam cylinder is filled with water and a potential difference is applied between the electrodes, the water behaves like
an ordinary electrical resistance and becomes hot, thus creating steam. The steam production rate can be controlled
